Use of an absorber for the regeneration of hydrotreating catalysts using a steam-air mixture

\n This article explores the processing of high-sulfur petroleum products into low-sulfur fuels without harming the environment. Specifically, it discusses the implementation of EURO-3 standards at the Bukhara Oil Refinery in Uzbekistan since 2022. The study examines the hydrodesulfurization process used to treat high-sulfur heavy fractions of oil. The primary aim of the research is to improve the method of oxidative regeneration of hydrotreating catalysts. Modern techniques are proposed for restoring the activity of used catalysts, one of which involves regeneration with a steam-air mixture. This new method offers numerous advantages over traditional approaches, including significant savings in energy and materials, reduced process duration, and decreased emissions of harmful gases into the environment. Consequently, this method not only enhances production efficiency but also plays a crucial role in protecting both the environment and human health.\n
